It could be like a room divider, or a series of curtains attached to a wall to help muffle noise or to soften the look of the room.
A curtain wall is covering of a building in which the outer walls are non-structural it can be made of a lightweight material reducing construction costs. When glass is used as the curtain wall, a great advantage is that natural light can penetrate deeper within the building. The curtain wall facade bears no weight from the building. The wall transfers horizontal wind loads through connections at floors or columns of the building.
A curtain wall is a non structural outer shell for an internally supported structure. They are non load bearing as they are in masonry or wood frame buildings where exterior walls are part of the support structure. Non load bearing interior walls are not considered curtain walls, just partition walls. For example,a modern skyscraper is supported by a steel skeleton & the curtain walls just hang from it to keep weather out. Basically , you can remove them entirely & the building will still stand.
